Business Approaches to OA

2

The Need for Open Architecture


To avoid spiraling costs and ensure supportability, the
USN has adopted OA core principles


Building a fleet that is interoperable and affordable


To be competitive Sensis recognizes the benefits of
OA


Reducing Time
-
to
-
Market and Increasing Cost Savings


Not always a driving requirement for our customers, but a driving
requirement from our internal stakeholders


This has lead to Sensis completing 5 successful SW
programs built on OA principles with 3 iterations of
OA design

Sensis and the USN have come to the same conclusion from
complementary, but different vantage points

Open Technology Development

in Sensis Processes


As part of embracing the OA principles, OTD is embedded in our formal
processes for development


Standard Operating Procedures and Work Instructions exist specific to
ensuring OA is incorporated in SW and HW


Sensis SOP OTD states that the benefits of an OTD strategy are:

1.
Enhancing agility to rapidly adapt and modify to user needed
capabilities

2.
Enhancing competitiveness by lowering cost and minimizing program
execution risk

3.
Encouraging decentralized innovation, shared discovery and forward
-
looking design

4.
Leveraging external and existing solutions, taking intelligent risk for
substantial gains, and factoring in life cycle cost advantages

5.
Enabling ease of changes, upgrades, or technology insertion

6.
Enabling joint integrated architectures and interoperability with other
systems

Sensis requires OA in our development process to be competitive

OTD starts before the program begins


Product Specification is evaluated for capability gaps at
proposal stage


Drives re

use starting at the top
-
level
requirements/architecture


Benefits of previous development programs are inherent


Architecture based upon OA Core
Principles


Key external and internal interfaces are isolated and
well
-
defined


Individual components can be modified without
impacting total architecture


Component designs are based upon life
-
cycle
affordability and modularity


COTS components for servers,
comms
, and
frequency synthesis


Reusable application software


SW components are written to allow adaptability


Demonstrated 2D/3D S

and L
-
Band signal
processing and AESA components
applicable to multiple radar platforms

The result is a system that is adaptable and reconfigurable to
address a variety of customer needs

SW OA Product Approach


Characteristics of the Open approach to SW
Products include


Platform independence


All Software is built on middleware


All software should be capable of “desktop
-
development”
rather than requiring the host platform


Strong APIs with a threading architecture


Component
-
Level Publish/Subscribe


Increases product reuse and configurability through loose
coupling of components


Isolation of algorithms/functions into configurable libraries


Allows algorithm development and improvement without
impacting transport and application framework

OA software approach allows software products to be developed
and refreshed independent of HW platform

Minimizing SW Development Risk


Striving for widely
supported, open source
technologies as SW
components and SW
platforms reduce the
impact during technology
upgrades


Long
-
Term Supportability is
correlated to Relative
Openness


Allows the HW components of
the product to be refreshed
without major impact to the
SW components

Choosing Open Source technologies increases supportability and
reduces risk in Total Ownership Cost

8

Quantifying Openness


Assessing SW/FW Reuse


Sensis Work Instruction defines a concrete, repeatable, and consistent
method for evaluating the level of reuse of a given component for a given
program within Sensis


Develops a “Reuse Level” that is equivalent to a effort factor to be used in
estimating development costs





A series of measurement factors are used to evaluate the
modifications required to estimate the level of reuse


Software, Pedigree, Requirements, Personnel aspects are included in the
evaluation


Working with current customer for developing a
methodology to evaluate total OA based on specific
metrics

Sensis is proactively and continuously reviewing our practices and
new innovation

HW OA Product Approach


Characteristics of the Open approach to HW Products
include:


Leverage commercial advancements for technology agility


Afford future growth options in functionality and performance without
disruptive and costly redesigns


Accommodate ready substitution for obsolete components


Employ commonly used standards for key interfaces


All like units interchangeable


No specialized tools or equipment to perform field service


Outcome is validated low production costs for Sensis
Open Technology approach for T/R Units


Derived Open Technology L

runs

outs


Benchmarked against an independently derived production cost for a
conventional T/R Unit prototyped to the same Specification Control
Document

Open Technology T/R Unit implementation is fully 1/3 lower in
production cost than its conventional design counterpart

11

Open Technology T/R Units


Sensis has employed Open Technology for the production of
Transmit/Receive (T/R) units


Major component of a phased array radar antenna


Architected to deliver high performance while being operationally flexible


Demonstrated specification compliant performance


Product line philosophy with the Unit and its constituents being advantageous for
multiple systems


Reduction in T/R unit production costs by at least a third


Quotations on competing approaches support this claim


Significant as the T/R units represent 50 to 70% of the array cost, which itself is
60 to 80% of the system cost


Reduction in operational and sustainment costs of up to 50%


Support system operational life
-
spans in excess of 20 years


Sensis asserts that to fully realize the promise of Open
Architecture the principles must extend internal to the Units


External form/fit/function/interface interchangeability at the unit level is insufficient

Sensis has validated the production cost
-
savings of OTD for HW
components while avoiding vendor
-
lock and obsolescence

, the following benefits of
an OA and Product Line approach are given:

For Industry these translate internally to the following
macro
-
level benefits:


Expanding Capability


Increasing Reuse
